BOAT-MOTOR.

Specification of Letters Patent.

Patented May i8, 1915.

Application filed January 9, i514. Serial No. 811,140.

To (f7/f w71 om, 'it mf/,f/ concern.

Bc it known that l, llnnnun P. BLAnnLY, a citizen o'l1 the UnitedStates, residing at Muskegon. in the county of Muskegon and State ol.lichigain have invented certain nen' and useful improvements inBoat-Motors, of which the following in a specification.

This invention relates to propelling 1nechanisins :nlapted to hedetachably connected to row boats and other small craft; and it referspaiticularlf,v to the type that conin'iscs an internal combustion engineconnected to drive a propellerl and constituting a unitary structure. Asheretofore oon.- structcd, the engine shaft and the propeller shaft havebeen connected by means ol' bevel p jears inclosed within a smallhousing or suppont. lo mountthe gears upon their shafts within thehousing has been an-nconvenient and thin-consuming operation. The gears.nun-cover, are relatively eX- pensive.

(.ne of the obiects of this invention is to avoid the trouble andexpense incident to the assembling ot the gears within the housing, andto substitute a clieaper and equally elficient drive.

in boat n'iotors oli the type rclerred to, 'the propeller in itsrotation exerts a constant tendency to turn the tiller, in consequenceof which the steersn'ian is continually obliged to exert strength tocounteract such tendency.

it is one of the objects of this invention to overcome the tendency ofthepropeller to turn the tillcr. n

A.. further object is 'to produce a boat inotor which will permit theboat to he steered while. the boat is coasting.

In the accompanying drawings Figure l is a, side elevation, partly insection, of a boat motor embodying the features of my invention. Fig. 2is a tragmental sectional view of the engine shaft and related parts.Fig. El is a section. on dotted lines 3-3 of Fig. Q. Fig. 4i is afragmental View of a leriible shaft comprised in the machine.

The engine and its accessories. and the means for securing the engine toa boat,

`1nay ho oil' any ordinary or preferred construction. and hence are notillustrated in detail.

l denotes a bracket ot' common form by means of which the motormay beattached to thestern ot a boat.

2 indicates an engine7 the frame of which may have an adjustableconnection with bracket l, as usual.

:l is the engine crank shaft.

4 is a vertical bearing sleeve whiclris rigid with the engine traine. Atiller 5 is rigidly secured to a sleeve 6 which is rotatably mounted.upon the bearing sleeve 4.-, the lower end of the sleeve G beingvertically slotted.

The means for connecting the engine shaft il to the propeller inclosedwithin a rigid tube 7, the upper portion of which is straight andextends within the tiller sleeve 6. The tube 7 is adjustably clamped inthe sleeve (3 by means ot' a holt 8 which Serves to draw the slottedportion of the Sleeve 6 into clamping contact with the tube. T he lowerportion of the tube 7 is curved rearwardly. To its loner, rear end isfixed a bearing sleeve 9. The connection between the tnhe fand thesleeve 9 may he of any suitable character, preferably such as willpermit Said parts to he conveniently separated when necessary. TheSleeve 9 may have a driving?T fit in the tube 7. In the sleeve f) isrotatably supported the propeller shaft l() having a propeller llmounted on its rear end.

The connection between the engine shaft il and the propeller shaft l0consists of a rigid shaft section 12 and a llexible shaft Section 'lheupper end of the shaft ,section l2 is tubular and lits slid-ably overthe lower end ot' the engine shaft 3. The shafts 3 and l2 may beconnected in any suitalgile way so as to rotate together; herein haveshown a key il carried bv the shaft l? and fitting' within alongitudinal keyway '.5 in `the shaft IThe flexible shaft section 'i3 isconnected at its upper end'to the lower end of the shult section 12 bymean-s oi a screw or equivalent member i6: and is conneeied at its lowerend to the 'forward end of the propeller shaft by a screw 17 or thelike.

Contact with the flexible shaft section 13, suitable means inay. ifdesired, be provided7 `such as a coiled spring i8 Htting Within the Toprotect the tube 7 from wear due fo' of Y v1,139,631v

the plunger 20 of the pumpfbeing operated by an eccentric portion a ofthe shaft 10 and by a spring 21.- The pump discharges vinto a tube 22which is connected through a iexible tube. (not shown) with the water,

'jacket of the' engine. for-med by the tube 7 is secured` a rudder plate23, said plate being suitably attached to\the tube and to the pump 19.The plate 23 is located between the aXiso the tiller .and the verticalplane of the propeller.

The engine 2 andthe tube 7 may be secured in an adjusted position withreference to the bracket `1 by any suitable 44means, a pbrtion of ameans ordinarily used for this purpose being shown at 24. The tube 7being vertically adjustable with relation to the tiller sleeve 6, andthe shaftssection l2 the` engine shaft 3, it will be seen that thepropeller 11 may. be raised or lowered to meet practical requirements.The tube 7 may be :filled with lubricant in'order to inshaftsection 13and the propeller shaft 10. When it is desirable to renew the supplyI'of lubricant in the tube 7, or to v'replace the coiled springl, thebolt 8 is loosened, the

tube 7 withdrawn from the sleeve G, and

the sleeve v.9 withdrawn from tbe tube 7, the separation .of the parts 7and 9 bringing the screw 17 into positionwbere it can be removed Uponthe removal of the screw 17, the shaft sections l2 and 13 may be with?vdrawn from the upper end of the tube 7.

It will be apparent that *the parts forining the driving connectionsbetween the engine and the propeller may be easily andv y ltheboat to besteered. Said plate also serves `to stifen the curved portion of thetube 7.

ll claim 'as my invention: l. ln a boat motor, a motor, a vertical shaftdriven by the motor, a'propeller shaft extending at an angle to thevertical shaft,

lll/'itbin the curve being, vertically adjustable with reference to surethe proper lubrication of the 'flexible eX-ible `shait'ting connectingsaid shafts,

means inclosing said flexible shafting, a removable wear-receivinglining for said inclosing means, and a propeller .on the propellershaft.

Q .'n a boat-motor, a motor, a vertical shaft driven` by the motor, apropeller shaft extending at an angle to the vertical shaft,

flexible shafting connecting said shafts,

-means inclosing said flexible shafting,. a

coiled spring surrounding the flexible shafting within. the inclosingmeans, said spring constituting a. wear-receiving lining for theinclosing means and being free from connection with the sbafting, and apropeller on the propeller shaft'. f

3. ln a boat motor, a` motor, a vertical shaft-section -driven by themotor, a rigid tube having a straight upper portion in'closing saidshaft-section and av rearwardly curved lower portion, a bearing sleevede tachably connected to the rear end or" the tube, a propeller shaftmounted in the bear ing sleeve, a flexible shaft-section in the curvedportion of the tube, the upper end of said flexible shaft-section beinglconnected to the vlower end of the vertical shaft-section, a. detachableconnection between'tbc `rear end of the flexible shaft-section and the4forward end of the propeller shaft, said de tachable connection beingrendered accessibleu/'ben the bearing sleeve is detached from the tube,and a propeller on the propeller shaft.

4. ln a boat motor, a motor, a rigid tube having a straight upperportion'and a rearwardly curved lower portion, a bearing sleeve theforward end of which is conn nected to tbe rear end of said tube, a.propeller shaft mounted in the bearing sleeve,

the forward end of said propeller shaft eX- tending forwardly of theforward endof .the sleeve, sba'fting driven by the motor and inclosedwithin said tube, said shating beine7 detachablyconnected to the forwardend ol' the propeller shaft, and a propeller on the propeller shaft. A
